python - Owlready：如何持久更改 base_iri 以使其保存？

Question

如果我更改base_iri本体的属性，则此更改在保存到文件后会丢失。如何更改 base_iri 以使此更改是永久性的？

自包含示例：

import owlready2 as owr

# create ontology in the default_world
onto = owr.get_ontology("https://w3id.org/old/onto#")

with onto:
    class Node(owr.Thing):
        pass
    
fname = "tmp.owl.xml"

new_iri = "https://foo.bar/onto#"
onto.base_iri = new_iri
print(onto.base_iri)
onto.save(fname)


w = owr.World()
onto2 = w.get_ontology(fname).load()
print(onto2.base_iri)

这输出

https://foo.bar/onto#
https://w3id.org/old/onto#

但我想要输出

https://foo.bar/onto#
https://foo.bar/onto#
